sf::Rect array (Solved)

[TechRogue]

I'm trying to use a for loop to check a Vector for an sf::FloatRect that contains a given coordinate set. However, when I do this:

Code: [Select]


sf::FloatRect Restraint[2];
Restraint[0](Left, Top, Width, Height);


my compiler complains:

error: expected constructor, destructor, or type conversion before ‘(’ token

Is this a mistake I'm making, or a bug in the library? Any insight would be appreciated.


SFML: 1.5
OS: Linux
Compiler: g++
IDE: Code::Blocks

It's your mistake, this syntax is wrong. What do you exactly want to achieve?

Maybe constructing a temporary sf::FloatRect and assigning it to the array element helps you.

Thanks for the quick reply. Essentially I have a vector ("Walkable") containing sf::FloatRects that make up the area that my character can move in if he's already inside the one that the mouse clicks on. This is for a point-and-click adventure game.

I'm currently trying to do this (pseudo-code):

Code: [Select]



for (int w = 0; w < Walkable.size(); w++)
{
    if Restraint[w].Contains(Mouse_Click_X, Mouse_Click_Y)
    {
        if (Restraint[w].Contains(Actor_Y, Actor_Y)
        {
            //handle movement;
            break;
        }
    }
}
       

I need to check a good amount of rects without hard-coding them all in.

[inlinevoid]

Code: [Select]


sf::FloatRect Restraint[2];
Restraint[0](Left, Top, Width, Height);


This should be changed to:

Code: [Select]


sf::FloatRect Restraint[2];
Restraint[0] = sf::FloatRect(Left, Top, Width, Height);


You can't call the constructor after initialization.

Hmm...it still doesn't work when I do that...

Code: [Select]

sf::FloatRect Restraint[2];
Restraint[0] = sf::FloatRect(Left, Top, Width, Height);

error: expected constructor, destructor, or type conversion before ‘=’ token|

[inlinevoid]

It should work fine...  It may be a bug with 1.5 though.  Try upgrading to 1.6(you won't have to change anything, the naming convention stayed the same).

Code: [Select]

Restraint[0] = sf::FloatRect(Left, Top, Width, Height);
It seems like you are trying to make this assignment in global scope and not inside a function. Hence the error.

That's right, this is all outside main(). I don't have access to my computer with the code on it right now, but I'll try that when I get home. Thanks!

That worked perfectly. Thanks for your help!
